Ing Chang-Ki

Ing Chang-Ki (Traditional Chinese: 應昌期, Simplified Chinese: 应昌期, Hanyu Pinyin: Ying Changqi (Yžng Chāngqī), died August 27, 1997) was a Chinese millionaire industrialist of Taiwan who learned to play Go when eight years old, and spent his lifetime promoting the game. Ing died at the age of 84.

He devised a proper set of rules: the Ing Rules -- simple enough for pre-school age children (except maybe for the ko rules)

He also devised playing equipment (see Ing stones) and donated much of it to Go federations worldwide
